mJtrRIOUS INSECTS.

the canker worm, the various cut worms, and other noxious 

 caterpillars ? A law carried out by a proper State entomolog- 

 ical constabulary, if it may be so designated, would compel the 

 idle and shiftless to clear their farms and gardens of noxious 

 animals. 



Among some of the injurious insects reported on by Mr. Riley, 

 the State Entomologist of Missouri, is a new pest to the cucum- 

 ber in the West, the Pickle worm (Phacellura nitidalis. Fig. 4G). 



46. Pickle Worm and its Moth. 



This is a caterpillar which bores into the cucumbers when large 

 enough to pickle, and which is occasionally found in pickles. 

 Three or four worms sometimes occur in a cucumber, and in the 

 garden a single one will cause it to rot. One of the most trouble- 

 some intruders in our graperies is the Vine dresser (Choero- 

 campa pampiuatrix. Fig. 47, larva and pupa; Fig. 48, adult), a 

 single caterpillar of which will sometimes "strip a small vine 

 of its leaves in a few nights," and occasionally nips off bunches 

 of half-grown grapes. 



Another caterpillar, which is sometimes so abundant as nearly 

 to defoliate the grape vine, is the eight spotted Alypi^ (Fig. 

 49; a, larva; b, side view of a segment). This must not be 

 confounded with the bluish larva of the Wood Nymph, Eudryas 

 grata (Fig. 50), which differs from the Alypia caterpillar in 

 being bluish, and in wanting the white patches on the side of 

 the body, and the more prominent hump on the end of the body.
